The originator of this apple, Joel LaValley of Amnicon Apples , suspects it is a seedling of Red Delicious ("but much better"). It has a good bit of the Red D conical taper, and some ribbing. The streaky red color, where it covers the green-yellow, is purer than Delicious's purple-tinged hue, and there are many light tan lenticel dots prominent in the blush. My samples are small and medium-sized. Now let's see about that "much better" part.
